Android实现QQ登录功能

QQ登录是一个非常简单的一个第三方应用，现在，我们就来实现一个QQ登录
首先下载两个jar包   这里上传不了jar包，所以可以到我的github中下载工程中libs中的两个jar包

网址：https://github.com/chengzexiang/qqlogin

打代码前，先把这些东西写上：

private static final String TAG = "MainActivity";
private static final String APP_ID = "1105602574";//官方获取的APPID
private Tencent mTencent;
private BaseUiListener mIUiListener;
private UserInfo mUserInfo;

在AndroidManifest.xml中加入权限

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

 <!-- 注册SDKActivity -->
  <activity
   android:name="com.tencent.tauth.AuthActivity"
   android:launchMode="singleTask"
   android:noHistory="true" >
   <intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data android:scheme="tencent1105602574" /> <!-- 开放平台获取的APPID -->
   </intent-filter>
  </activity>
  <activity android:name="com.tencent.connect.common.AssistActivity"
   android:theme="@android:style/Theme.Translucent.NoTitleBar"
   android:screenOrientation="portrait"/>

Xml布局中的

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:app="http://schemas.android.com/apk/res-auto"
 android:orientation="vertical"
 xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
 android:layout_height="match_parent" tools:context="com.bwei.czx.czx0914qq.MainActivity"> 

 <Button
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:text="登录"
  android:id="@+id/login"/>
 <TextView
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:id="@+id/name"/>
 <ImageView
  android:layout_width="100dp"
  android:layout_height="80dp"
  android:id="@+id/img"/> 

</LinearLayout>

下面开始MainActivity中的代码

public class MainActivity extends AppCompatActivity {
 private static final String TAG = "MainActivity";

 private Tencent mTencent;

 @Override

  setContentView(R.layout.activity_main);
  //传入参数APPID和全局Context上下文
  mTencent = Tencent.createInstance(APP_ID, MainActivity.this.getApplicationContext()); 

  initView();
  login.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
    mIUiListener = new BaseUiListener();
    //all表示获取所有权限
    mTencent.login(MainActivity.this,"all", mIUiListener);
    mUserInfo = new UserInfo(MainActivity.this, mTencent.getQQToken()); //获取用户信息
    mUserInfo.getUserInfo(mIUiListener);
   }
  });
 } 

 private void initView() {
  login = (Button) findViewById(R.id.login);
  name = (TextView) findViewById(R.id.name);
  img = (ImageView) findViewById(R.id.img);
 }
 /**
  * 自定义监听器实现IUiListener接口后，需要实现的3个方法
  * onComplete完成 onError错误 onCancel取消
  */
 private class BaseUiListener implements IUiListener { 

  @Override
  public void onComplete(Object response) {
   Toast.makeText(MainActivity.this, "授权成功", Toast.LENGTH_SHORT).show();
   Log.e(TAG, "response:" + response);
   JSONObject obj = (JSONObject) response;
   try {

    mTencent.setAccessToken(accessToken,expires);
    QQToken qqToken = mTencent.getQQToken();
    mUserInfo = new UserInfo(getApplicationContext(),qqToken);
    mUserInfo.getUserInfo(new IUiListener() {
     @Override
     public void onComplete(Object response) {
      Log.e(TAG,"登录成功"+response.toString());
      if(response == null){
       return;
      }
      try {
       JSONObject jo = (JSONObject) response;
        Toast.makeText(MainActivity.this, "登录成功",
          Toast.LENGTH_LONG).show();
       String nickName = jo.getString("nickname");
       String figureurl_1= jo.getString("figureurl_1");
       name.setText(nickName);
       ImageLoaderConfiguration configuration = new ImageLoaderConfiguration.Builder(MainActivity.this).build();
       ImageLoader.getInstance().init(configuration);
       ImageLoader.getInstance().displayImage(figureurl_1,img);
      } catch (Exception e) {
       // TODO: handle exception
      }
     } 

     @Override
     public void onError(UiError uiError) {
      Log.e(TAG,"登录失败"+uiError.toString());
     } 

     @Override
     public void onCancel() {
      Log.e(TAG,"登录取消"); 

     }
    });
   } catch (JSONException e) {
    e.printStackTrace();
   }
  } 

  @Override
  public void onError(UiError uiError) {
   Toast.makeText(MainActivity.this, "授权失败", Toast.LENGTH_SHORT).show(); 

  } 

  @Override
  public void onCancel() {
   Toast.makeText(MainActivity.this, "授权取消", Toast.LENGTH_SHORT).show(); 

  } 

 }
 @Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  if(requestCode == Constants.REQUEST_LOGIN){
   Tencent.onActivityResultData(requestCode,resultCode,data,mIUiListener);
  }
  super.onActivityResult(requestCode, resultCode, data);
 }
}
